Flight
The easiest way to get here by plane is Madison airport. This can be expensive, though, so the next best option is Milwaukee airport. Keep in mind there's a 1.5 hour drive from Milwaukee to Madison.
Travel Note
Any hotel in the greater Madison area should be fine! Staying downtown will be very expensive, but there are lots of options in the surrounding areas. Our house is on the west side of Madison, and the picnic will be held on the South side of Madison. Please keep in mind that there are a few huge events happening in Madison this weekend. That'll make downtown very crowded in both traffic and people booking hotels. If you haven't booked your hotel already, please do so ASAP!
